Exposure Science for Healthier Environments and Workplaces

good air for all

Visualizing the Invisible
Indoor air freshness is essential for health and productivity in shared common spaces. This is especially true in these times!

The global coronavirus pandemic has drastically altered our lives. Suddenly air quality issues have jumped to the forefront of daily health concerns. However, not in terms of the traditional air pollutants such as particulate matter, nitrogen oxides, carbon monoxide, ozone, but in terms of biological threats, namely: SARS-CoV-2. Understanding how the virus survives and propagates through our environment is vital to knowing how we can best survive its presence before we reach herd immunity through mass vaccination. Based on our current understanding of the virus, not only is the virus transmitted via large droplets but it is also very likely transmitted via much smaller exhaled aerosol particles. Furthermore, new more infectious variants of the virus are currently on the rise.

At ASL, we now provide air quality control systems that monitor and improve indoor air 'freshness' through measurements of several pollutants and environmental factors. In response to these real-time measurements, our system can automatically control a number of devices that will create a healthier fresher indoor air quality for safer and healthier common spaces with low virus concentrations. See our Air Quality Systems.



A world where decision-making for good air quality for all populations is not prevented by data scarcity.


The indoor environment is where we spend most of our time. Our real-time air monitoring systems control devices that create fresh indoor air environments. Clean air environments prevent the transmission of disease and improve people’s long-term health.


Offer consulting services in the domains of exposure science, indoor and outdoor air quality, environmental monitoring and modeling to create and support healthier environments.


Measurements and monitoring are the basis of exposure science. Our lab measures air pollutants via integrated and real-time device monitoring instruments. Our team has over 15 years of fieldwork experience in Switzerland, Europe, USA, as well as in Africa and Asia in support of health studies.
